Problem conclusion

Temporary fix

Comments

• New function APAR to add zEDC usage statistics into the SMF30
  record.
  
  The following zEDC performance data will be collected across the
  entire set of PCIE Functions (PFIDs):
    . Total number of zEDC compression and decompression requests,
      both supervisor and problem state.
    . Total number of Problem State zEDC compression and
      decompresion requests
    . Total queue time in microseconds
    . Total execute time in microseconds
    . Deflate Statistics for the number of bytes of uncompressed
      input and compressed output
    . Inflate Statistics for the number of bytes of compressed
      input and uncompressed output
  
  
  The following document is updated with the SMF30 zEDC Usage
  Statistics information.
  
  SA38-0667  HBB7790  z/OS MVS System Management Facilities (SMF)
  
  Chapter 14. SMF records
  Under the section "Record Type 30 (1E)  Common Address Space
  Work, Record Mapping  Header/self-defining section",
  add the zEDC Usage Statistics triplet fields which are located
  in the header/self-defining section, and then
  add the zEDC Usage Statistics section.

  zEDC Usage Statistics section
  
  This section contains various counters for the zEDC Usage
  statistics for the period that the record represents.
  This section is only produced when zEDC Compression and
  Decompression activities occur during the period.
  
  Triplet Information: This section is located on the record using
  the following triplet fields, which are located in the
  header/self-defining section:
  
  Offset  SMF30USO - Offset of zEDC Usage Statistics section
  
  Length  SMF30USL - Length of zEDC Usage Statistics section
  
  Number  SMF30USN - Reports the number of zEDC Usage Statistics
                     sections on the current record. This can be
                     0, indicating the zEDC Usage Statistics
                     section does not exist.
